### Trailing Commas
Print trailing commas wherever possible.
Print trailing commas wherever possible when multi-line. (A single-line array,
for example, never gets trailing commas.)
Valid options:
* `"none"` - No trailing commas.
* `"es5"` - Trailing commas where valid in ES5 (objects, arrays, etc.)
* `"all"` - Trailing commas wherever possible (function arguments). This requires node 8 or a [transform](https://babeljs.io/docs/plugins/syntax-trailing-function-commas/).
* `"all"` - Trailing commas wherever possible (including function arguments). This requires node 8 or a [transform](https://babeljs.io/docs/plugins/syntax-trailing-function-commas/).
